Robin Roberts

In late December, Robin Roberts posted a Facebook message that expressed gratitude to all that have helped her through a difficult period in her life, one that included a bone marrow transplant to treat a rare blood disorder.

The Good Morning America anchor also referenced girlfriend Amber Laign for the first time publicly in the post, coming out as gay.

Having spent more of 2013 fighting for her life after being diagnosed with a rare blood disorder, Robin Roberts took to Facebook today and expressed gratitude to all who have been by her side during this difficult time.

Including her girlfriend. Yes, in a subtle, sentimental way, Roberts revealed to the world today that she's gay.

Robin Roberts will resume her full-time duties with the program following Labor Day, making the announcement in an interview with Vanity Fair and joking about how she's managing to sneak in one more four-day work week due to the holiday.

Following her well-publicized battle with myelodysplastic syndrome - which included a bone marrow transplant late last year - Robin Roberts has signed a deal with Grand Central Publishing to release a memoir next spring.
